Short answer: the Huawei Sound Joy 2, if you are buying new. The Huawei Sound Joy ranks higher than the Ultimate Ears Boom 4 (#40 vs #112 of 177 medium speakers) but is discontinued; its replacement, the Huawei Sound Joy 2, is rated 3.5/5 at $154.73 and is still sold new.
What the Ultimate Ears Boom 4 does well: A tough waterproof speaker that floats, with USB-C charging, app EQ and pairing with other UE speakers. It plays in stereo from a single unit, unlike the Huawei Sound Joy. Watch for: Not much improvement over the old ones.
The Huawei Sound Joy is the better-sounding, longer-running pick. A waterproof speaker with a separate tweeter, long battery life and good loudness, with a Devialet mode for its best sound. It is rated for 26 hours of battery against 15 for the Ultimate Ears Boom 4. It supports AAC Bluetooth, which the Ultimate Ears Boom 4 lacks. The catch: Boosted treble, not quite as deep of bass as a JBL Charge 5.
Buy the Huawei Sound Joy 2, the replacement for the discontinued Huawei Sound Joy; it is rated higher for sound quality than the Ultimate Ears Boom 4.
